The 1,136-seat Beckman Auditorium is operated by Caltech Public Programming as a campus and community service. A broad range of performing arts, lectures, films, classes, and entertainment events are offered throughout the academic year.

The auditorium's unique architecture was meant to be a "monumental structure" anchoring the north end of campus. It was a gift of Arnold O. and Mabel Beckman. Arnold Beckman was a Caltech alumnus (PhD '28), faculty member, and chairman emeritus of the Board of Trustees.
